Find your county's Radon Information Center
Seventeen local health departments act as regional radon centers, covering all 72 Wisconsin counties. They answer questions and provide low-cost test kits.
How the centers work
Wisconsin’s radon program runs through regional Radon Information Centers. Each one is based at a county or city health department and serves that county plus its neighbors. Staff can explain your test result, tell you whether to retest, and help you find low-cost kits. For current phone numbers and websites, see the DHS Radon Information Center page, which is updated as contacts change.
The statewide line is 1-888-LOW-RADON (1-888-569-7236).
